35783ec07c [PATCH] IB/ipath: fix a bug that results in addresses near 0 being written via DMA
We can't tell for sure if any packets are in the infinipath receive buffer
when we shut down a chip port.  Normally this is taken care of by orderly
shutdown, but when processes are terminated, or sending process has a bug, we
can continue to receive packets.  So rather than writing zero to the address
registers for the closing port, we point it at a dummy memory.

8307c28eec [PATCH] IB/ipath: support more models of InfiniPath hardware
We do a few more explicit checks for specific models, and now also support the
old PathScale serial number style, or new QLogic style.

This is backwards compatible with previous versions of software and hardware.
That is, older software will see a plausible serial number and correct GUID
when used with a new board, while newer software will correctly handle an
older board.

being held.  ACK packets are now sent without requiring synchronization with

57abad25f8 [PATCH] IB/ipath: fix lost interrupts on HT-400
Do an extra check to see if in-memory tail changed while processing packets,
and if so, going back through the loop again (but only once per call to
ipath_kreceive()).  In practice, this seems to be enough to guarantee that if
we crossed the clearing of an interrupt at start of ipath_intr with a
scheduled tail register update, that we'll process the "extra" packet that
lost the interrupt because we cleared it just as it was about to arrive.

f5f99929ac [PATCH] IB/ipath: fixed bug 9776 for real
The problem was that I was updating the head register multiple times in the
rcvhdrq processing loop, and setting the counter on each update.  Since that
meant that the tail register was ahead of head for all but the last update, we
would get extra interrupts.  The fix was to not write the counter value except
on the last update.

I also changed to update rcvhdrhead and rcvegrindexhead at most every 16
packets, if there were lots of packets in the queue (and of course, on the
last packet, regardless).

I also made some small cleanups while debugging this.

With these changes, xeon/monty typically sees two openib packets per interrupt
on sdp and ipoib, opteron/monty is about 1.25 pkts/intr.

I'm seeing about 3800 Mbit/s monty/xeon, and 5000-5100 opteron/monty with
netperf sdp.  Netpipe doesn't show as good as that, peaking at about 4400 on
opteron/monty sdp.  Plain ipoib xeon is about 2100+ netperf, opteron 2900+, at
128KB

13aef4942c [PATCH] IB/ipath: reduce overhead on receive interrupts
Also count the number of interrupts where that works (fastrcvint).  On any
interrupt where the port0 head and tail registers are not equal, just call the
ipath_kreceive code without reading the interrupt status, thus saving the
approximately 0.25usec processor stall waiting for the read to return.  If any
other interrupt bits are set, or head==tail, take the normal path, but that
has been reordered to handle read ahead of pioavail.  Also no longer call
ipath_kreceive() from ipath_qcheck(), because that just seems to make things
worse, and isn't really buying us anything, these days.

Also no longer loop in ipath_kreceive(); better to not hold things off too
long (I saw many cases where we would loop 4-8 times, and handle thousands (up
to 3500) in a single call).

f37bda9246 [PATCH] IB/ipath: memory management cleanups
Made in-memory rcvhdrq tail update be in dma_alloc'ed memory, not random user
or special kernel (needed for ppc, also "just the right thing to do").

Some cleanups to make unexpected link transitions less likely to produce
complaints about packet errors, and also to not leave SMA packets stuck and
unable to go out.

A few other random debug and comment cleanups.

Always init rcvhdrq head/tail registers to 0, to avoid race conditions (should
have been that way some time ago).

17311c03c3 [PATCH] IRQ: Use SA_PERCPU_IRQ, not IRQ_PER_CPU, for irqaction.flags
IRQ_PER_CPU is a bit in the struct irq_desc "status" field, not in the
struct irqaction "flags", so the previous code checked the wrong bit.

SA_PERCPU_IRQ is only used by drivers/char/mmtimer.c for SGI ia64 boxes.

a99e4e413e [PATCH] pi-futex: fix mm_struct memory leak
lock_queue was getting called essentially twice in a row and was
continually incrementing the mm_count ref count, thus causing a memory
leak.

Dinakar Guniguntala provided a proper fix for the problem that simply grabs
the spinlock for the hash bucket queue rather than calling lock_queue.

The second time we do a queue_lock in futex_lock_pi, we really only need to
take the hash bucket lock.
